MCS-021 : DATA AND FILE STRUCTURES

IGNOU MCS-021 Exam Most Questions


(1.)Write an algorithm to sort "N" numbers  using Bubble sort. Also, show that bubble
sort algorithm, on average, makes 0(N2) comparisions while sorting a list of N
elements

(2.)Show step-by-step construction of a B-Tree  (t=3) resulting from the insertion of the
following keys. A, S, T, M, U, K, j, B, G, N Also, show deletion of Key 'U' and 'K' from
the B-Tree constructed above.

(3.)What is a height-balanced tree ? Construct  an AVL so that tree for the following elements :
6, 3, 15, 24, 7, 89, 12, 34, 2 Show all the intermediate steps.

(4.) What is a Dequeue ? Write an algorithm to  insert and delete to the node in a Queue.

(5.) Write an algorithm to implement Heap using  linked list. The algorithm should clearly perform PUSH and POP list operation.

(6.)Write an algorithm to reverse the order of  nodes in a doubly linked list with header node.

(7.) Differentiate between the Kraal's and  prim's algorithm based on their principle,
operation and running time. Also know write any two applications of minimum cost spanning
tree.

(8.)Differentiate between Indexed file  organisation and Indexed sequential file organisation. Also, write any four disadvantages of sequential file organization

(9)Consider the algorithm given below : 10
(i) scanf ("%d", &n);
(ii) {for (int i = n; < = n * n; i = n + 10)
(iii) (for (int j = 1; j <>= n; j++)
(iv) printf ("%d", n/i + j);}}
Calculate to the complexity (both space and time) of the above code by using Big "0"
notation

(10.)Write an algorithm for Heapsort. Write step by step to the  working of algorithm for the following set of data :
9, 16, 43, 27, 91, 33, 21, 7, 3,4

(11.)Write an algorithm for adding two polynomials. Algorithm should take the two
polynomials as input and display the resultant polynomial.

(12.)What is a BST ? Explain with an example. What are its limitations

(13.)Find the order of the function 3n + 2.

(14.)Write the functions to perform Push and  Pop operations of stack using pointers.
Using above functions, write an algorithm to convert a given infix notation to its
equivalent postfix notation

(15.) Design algorithms for various operations  performed on circularly linked list.

(16.) What are the advantages of using lists than  arrays while implementing a stack ? Explain.


(17.) Write a procedure to find minimum cost  spanning tree for a graph using Prim's
algorithm.

(18.) Explain the process of creating a Splay Tree  using an example
